Package: winbind
Version: 2:3.3.1-1
Severity: important
upgrading to lenny from etch breaks things:
authentication in pptpd stops working
error "MS-CHAPv2 mutual authentication failed." logged at client, and no
VPN established
found workarounds:
1. use radius
2. upgrade winbind to version from sid (2:3.3)
How does this pptpd implementation interface with winbind?
